The term 'CERTAIN TENDENCY' can be summarized as a BIAS, which is a four-letter word. A BIAS is an inclination or prejudice for or against one person or group, especially in a way considered to be unfair. It is often based on preconceived ideas or stereotypes and can lead to discrimination and unequal treatment. BIAS can also refer to a tendency to believe that some people, ideas, or facts are better than others.
